Subject[PATCH] PCI: xilinx: Modify error handling
Failure of of_get_next_child returns NULL, not an ERR_PTR. Use
appropriate error code -ENODEV to be returned on failure instead.

The Coccinelle semantic patch used to find this issue is as follows:
@@
expression E,E1;
@@

if (
* E == NULL
) { <+... when != E = E1
PTR_ERR(E)
...+> }
